A Varian V-4500 electron-spin paramagnetic rescnance spectrometer and associated 6-inch electromagnet have been placed in operation. Measurements of the magnetic field are made with a Pound-Watkins spectrometer constructed in the laberatory. Studies have been made of single crystals of LiF which have received tbermal neutron irradiation dosages up to 72 hours in a flux of 2.3 x 10/sup 12/ cm/sup 2/-sec. The observed resonance envelope and hyperfine splittings are not in agreement with F-center theory. A dependence of the hyperfine splitting on crystal orientation in the magnetic field has been noted. Crystals of KCl, KBr, KI, NaF, NaCl, RbI, CsBr, and CsI which have received reactor or gamma irradiation are under investigation. (auth)
